“The Separation”The separation of church music and secular music during the Baroque period was the beginning of something new. Many people had no idea that the instruments they used during the Renaissance period could do more than they had been doing with them. This brought a new meaning of music and life into the world. It was a great change for music, instruments, and even people. Church music, also known as sacred music, was well known in the Renaissance Era, while the secular music will become more known in the Baroque Era. Let’s dive in by first clarifying what exactly was the Baroque Era, then distinguishing what caused the separation of church music and secular music during the Baroque Era.

“The term Baroque era describes the style or period of European music between the years of 1600 and 1750. The term Baroque was derived from a Portuguese word meaning "a pearl of irregular shape." The word Baroque was initially used to imply strangeness, abnormality and extravagance, applying more to art than music. It is only in the 20th century that this term has been employed to refer to a period in music history” ( Bailey). The power of music was discovered during this time The Baroque period was the beginning of a new era, it is known for its many forms of church music and most of the sacred, or religious, music of the Baroque was written specifically to be performed as part of a church service. Baroque music has become increasingly popular over the last fifty years and I believe that it will continue to do so in the years to come. There are many differences between this era’s music and today’s modern music. Things such as pitch, timbre, and performance techniques have changed quite a bit over time and are constantly changing as we speak. Differences between loud and soft, solo and ensemble play an important role in many Baroque compositions. The Baroque Era introduced instruments such as violins, flutes, recorders,...

Lab #2 – Separation of a Mixture of Solids
Abstract
The mixed solution contained benzoic acid, iron, table salt, and sand. When separated using water, fuel, or a magnet, their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used, the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated.
Introduction
The objective of this lab was to separate and examine different solutions within a solution. In order to separate each element different methods and techniques were used. Separating the iron filings wasn't difficult or lengthy; however it did require patience and a steady hand. Separating the benzoic acid and the table salt took the longest because it needed to air dry causing the water to evaporate.
Methods
While the water was boiling with the table salt, sand, and benzoic acid, the water got thick. It was difficult to separate the solids because they would get stuck to the bottom of the Styrofoam cup. In order to separate the iron filings a magnet was used. The solution first needed to be spread out on a piece of paper. As the magnet was ran over the solution, the iron filings were picked up. It took several tries to get all of the iron picked up. To separate the sand, the burner and distilled water was used. As it boiled, it had to be stirred to make sure it...

Title: Separation of Mixtures and Solids
Purpose: The purpose of this experiment was to practice the process of separating mixtures of different solids.
Procedure:
This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand, benzoic acid, iron fillings, and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the iron pieces. Then to separate the sand from the rest of the mixture I heated the mixture with water in a beaker and when I poured the heated liquid into a cup the sand remained in the bottom of the beaker. Lastly to separate the benzoic acid and sodium chloride I used a filtration system and the sodium chloride and water drained into a cup while the benzoic acid remained on the filter.
Data:
Item | Mass (grams) |
Weighing Dish | 0.6 g |
Dish + Mixture | 7.9 g |
Net Mass of Mixture | 7.3 g |
| Mass (Grams) | Percent of Mixture |
Iron Fillings | 1.8g | 26.9% |
Sand | 1.5g | 22.4% |
Table Salt | 1.9g | 28.4% |
Benzoic Acid | 1.5g | 22.4% |
Total: | 6.7g | |
Observations:
Some things I observed during this laboratory include the magnet not picking up some of the smaller iron particles without getting really close to the solids mixture. Also both the sodium chloride had somewhat of a sour smell when heated....

...﻿Separation of Iron, Salt and Sand
Separating a mixture is an example of a physical change. There are several ways to separate a mixture. The use of one's hands in pulling the parts of a mixture apart is one example. Filtration is another way to separate mixtures. Filtration is the separation of a heterogeneous (not alike, different) mixtures, by adding a solvent and passing the resulting mixture through a fine mesh or filter. Evaporation of a homogeneous (alike, same) mixture will reveal any solid particles which were dissolved in the original mixture.
Materials:
iron filings sand
salt water
magnet hot plate
filter paper 50 mL & 100 mL beaker
funnel tongs
Directions:
1. Combine 1 g of iron filings, 1 g of salt and 1 g of sand in a petri dish.
2. By using a magnet remove the iron filings.
3. Place the mixture which contains salt and sand in a 100 mL beaker.
4. Add 50 mL of water to the mixture.
5. By using filter paper and a funnel separate the sand from the mixture. The sand will
be left on the filter paper, leaving a mixture of salt and water.
6. Using a hot plate bring the salt and water to a boil. Continue boiling while
decreasing heat until almost all of the water has evaporated.
7. Using tongs remove the beaker from the hot plate and place it on a hot pad.
8. The salt will be left at the bottom of the beaker.

...Separation of a Mixture of Solids
I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came to the conclusions that the salt would need hot water to separate from the mixture, the benzoic acid would need cold water to separate, the sand would settle on its own, and the iron filings could be separated with a magnet. My flow sheet was pretty accurate. We started by separating the iron, which was by far the coolest part, watching the magnet pull up every tiny filing of iron out of the mixture was awesome. Getting that iron onto the scale and off of the magnet was the hard part though. I removed the plastic, which I had wrapped around the magnet, but when I removed the plastic the iron filings simply left the plastic and continued to cling to the magnet, so I had to scrape them off and onto the scale by hand. Separating the sand was also pretty straightforward, we boiled the mixture in water in the beaker and the sand settled on its own. We poured out the solution into a paper cup, leaving the sand in the beaker. We attempted to heat the sand slowly to dry it...

...Introduction
Parliament is the key institution within the legislative arm. Parliament's primary role is to make laws, called Acts or Statutes, which outline the standards of behavior expected of members of the community. Parliament is able to make laws because the Australian Constitution has vested supreme law-making power in an elected Commonwealth Parliament. All laws are designed to protect human rights and to foster the achievement of social cohesion.
All other federal institutions of government are sourced from parliament, as an enabling Act must be passed to create them.
Executive Arm
The primary institution in the executive arm is the government, however the government's functions are assisted by the mass of government departments and agencies. These bodies have been vested with executive powers to enforce and administer the laws made by parliament (e.g. The Police Department, via police officers, investigates breaches of criminal law. The police identify and arrest offenders, and offenders are then prosecuted in a criminal court, with the intention that they will be convicted and punished for their offence[s]).
Judicial Arm
Just as the government is the principal institution in the executive arm, the courts fill this role in the judicial arm. The courts are vested with judicial power to administer justice to solve disputes. Judges preside in courts in the criminal and civil jurisdictions, to determine whether legal entities have broken a law, and...

..."The 'separation of powers' is incomplete within the current unwritten UK constitution."
The ‘separation of powers’ is doctrine of the UK constitution first termed by Montesquieu, a French political philosopher, in his 1748 book De l'esprit des lois (The Spirit of the Laws) he argues that there are three bodies of government – the executive, legislature and judiciary – which each have a discrete area of power with clear functions that no other body can imitate: this is true ‘separation of powers’. The purpose of which is to limit state power so that no element has an abuse of power hence protecting civil liberties. By Montesquieu’s definition, the separation of powers is incomplete as there is clear overlap between the different branches of government, notably the legislative and executive. Contrastingly, the revisionist definition of the separation of powers as, remarked by Lord Bingham, claims that while the doctrine of the separation of powers is weak by the terms of the classic characterisation, “the separation between the exercise of judicial powers on the one hand and legislative and executive powers on the other is total or effectively so” This convincing revaluation of the separation of powers principle indicates that under the new “partial” definition, the separation of powers is a clear, complete doctrine in the UK unwritten constitution....

...﻿1. Explain the Doctrine of the Separation of Powers and how it operates in Australia
The Doctrine of Separation of Powers is widely used in many democracies around the world. It is based on the idea that in order to maintain civil liberty, there is a need to separate the institutions that make the law, those that execute it, and those which adjudicate the law. The concept was defined by Charles de Secondat, Baron de Montesquieu in Spirit of Laws1, this framework allows checks and balances in the system, with power divided into three branches of government ensuring that no individual branch is able to wield complete power, nor abuse it, thus protecting the liberty of the citizens.
“The dignity and stability of government in all its branches, the morals of the people and every blessing of society, depends so much upon an upright and skillful administration of justice, that the judicial power ought to be distinct from both the legislature and the executive, and independent of both, so that it may be a check upon both, as both should be checks upon that”2.
In Australia, the Doctrine of Separation of powers is constructed through the Commonwealth of Australia Constitution Act. The power to make and manage law is divided between the following three groups:
Legislative power3 – held by the Parliament, which makes and amends the law. The Australian Parliament is made up of the Queen, the Senate, and the House of Representatives....
